Cross-linkable nanocomposite anticorrosion coating

DWPI Title: Depositing nanocomposite anticorrosion coating on corrodible metal, involves depositing bilayer on surface of corrodible metal and crosslinking crosslinkable polymer, where the bilayer comprises a layer of a crosslinkable polymer and a layer of dispersed and aligned platelet particles
Abstract: Nanocomposite anticorrosion coating can be achieved by depositing alternating, multilayers of a cross-linkable polymer and dispersed and aligned inorganic platelets followed by cross-linking of the cross-linkable polymer. The cross-linkable polymer can be an externally cross-linkable polymer that is cross-linked by diffusing a cross-linking agent into the deposited multilayer coating. Alternately, the cross-linkable polymer can be a functionalized cross-linkable polymer that is cross-linked by self-curing, thermal heat curing, or light (e.g., UV) following deposition of the multilayer coating.
Use: The method is useful for depositing a nanocomposite anticorrosion coating on a corrodible metal.
Advantage: The coating has excellent corrosion barrier properties, barrier properties, mechanical integrity, film properties and chemical and mechanical stability. The method eliminates required and extensive processing of materials using harsh chemicals, such as production of graphene/graphene oxide.
Novelty: Method for depositing a nanocomposite anticorrosion coating on a corrodible metal, involves depositing at least one bilayer on a surface of the corrodible metal, and crosslinking the crosslinkable polymer, where the bilayer comprises a layer of a crosslinkable polymer and a layer of dispersed and aligned platelet particles.
